To what extent does air pollutant-induced semen damage contribute to male infertility? STOTEN_journal pollution airpollution airpollutant malehealth menshealth infertility fertility news research
By Dr. Sanchari Sinha Dutta, Ph.D.Apr 25 2023Reviewed by Lily Ramsey, LLM A study published in the Science of the Total Environment Journal investigates the contribution of air pollutants-induced semen damage to the risk of infertility.
Studies conducted in animals have shown that air pollutants, including particulate matter , reduce sperm quality and impair spermatogenesis, leading to reduced fertility. During the study follow-up period of 12 months, the infertility rate was assessed among the participants. Infertility was defined as being unable to get pregnant after unprotected intercourse within 12 months.
Important observations The analysis of the effects of air pollutants on semen parameters during the 90-day exposure period revealed significant negative effects of SO2 and O3 on sperm morphology and progressive motility and vitality, respectively. The impact of PMs and NO2 on sperm morphology and sperm deformity index was observed during the spermatocytogenesis period. Regarding sperm deformity index, the effects of PMs and O3 were observed during the epididymal storage period and sperm motility development period, respectively.
